This is an Unstable Gas deck, made for PvP1. It works very well, and I'd be glad to try it in a competition or something like that. The unupped one is not a rush deck, but the upped one may be considered one.

General strategy: Owl's Eyes first, fly them when you can. They are there to soften up your opponent, while providing super creature control to help you stay alive. Hold the gases in your hand, otherwise they might get destroyed. Play them all when you have enough of them to blow your opponent up in one turn.
The nymph is a very good addition, but I don't think it's necessary. Perhaps you could replace it with a dragon.
Upped, I would play something like this if I had the electrum to upgrade the cards (yes, it's a bit different):

With Elite Fireflies, you can be mono air, which speeds up everything. Fireflies come out fast and if they aren't killed, they can damage your opponent enough to blow him up quickly. Actually, I am not sure about the nymph there, she is slow compared to the rest of the deck and the gases you draw are probably enough with those fireflies eating your opponent. The Eagle's Eyes and Improved Fogs could also be replaced with wyrms if more speed is desired, but I like the way it is.
I hope you like it.
